RAILWAY-CHAIR.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed November 4, 1907. Serial No. inane.

fication,

The object of my invention is to construct an improved railway chairwhich will facilitate the laying and securing of the rails therein,displense with the wood chucks or wedges and fis plates usuallyemployed, and permit of lineal expansion and contraoon of said rails.

By my construction of chair, the greater the weight put upon the railswhen laid the more securely are they held. ,1

According to my invention }preferably construct my improved chairs oftwo .fixed jawsupon each side with a suitable space between each pair,within which hinges or pivots a loose jaw of peculiar form, whose innerface is shaped in conformity with the sides of the rail. The bottom ofthe rail, when in position within the chair, rests or beds upon aprojecting wing or heel of the loose jaws in such a manner as to causethe upper potion of the jaws to grip or bear against the sides of therail. A bolt or cotter. passing through the fixed jaws and behind eachloose jaw holds the latter in position against the sides of the rail,and prevents the rail being lifted out of the chair.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a sectional end view of my improvedrailway chair, showing position of loose jaws when about to insert asection of rail. Fig. 2 is a side view of my improved railway chairshowing the rail secured in position within the chair. Fig. 3 is anendview of Fig. 2. Fig. 4 is a plan of Fig. 3.

Similar letters refer 'to similar parts throughout the several views.

When o .strueting my improved chair I prefers .orm the/same with twofixed jaws or guidm standards A, A, upon each side. Hinging or pivotinbetween each pair of jaws A, A, u )on bo ts or studs B, is a loose jawCof special form, whose inner face correslponds in shape with the sidesof the rail D.

he loose jaws C are turned back upon their pivots B when requiring toinsert the rail, but

are restricted in such movement by a sto or projection F coming incontact with a ri G on the base plate H of chair.

Upon placing the rail D.in my imprqved chair, it is lowered between thefixed jaws A, and coming into contact with a projecting heel or win J ofeach loose jaw C, sedFig. 1, automatica ly tilts the latter forwarduntil they come in contact with the sides of the rail. The wings J beingnow brought into osition, see Fig. 2, serve as a support or caring forthe rail which is also shared by the looseqaws aforesaid, so that themore weight'pu't upon the rail and by the rail upon the wings J, thegreater the nip or grip of the loose jaws upon the sides of said rail,and the more rigid it becomes.

The loose jaws C are secured in position after the insertion of the railby cotters, pins, or bolts K passing through the fixed aws A, A, andbehind the loose jaws C; in this manner the rail is securely fixedwithin the chair.

To prevent undue lineal movement of the rails and allow for expansionorcontraction of the same, I preferably form a stud L upon one of theloose jaws, which, when the jaws engage with the rails, fits within .asuitable recess M in the rail.

When dealing with rail joints, I preferably form the chairs with threefixed and two loose jaws upon each side.

What I claim as my invention, and desire to secure by Letters Patent,is-

In a railroad chair, the combination, with a base-plate provided withtwo standards on each side of its middle portion, of opposedclamping-jaws having their lower parts piv oted between the saidstandards and provided with heels for the rail to rest on and havingalso lugs at their upper parts for gripping the rail, said lugs beingmovable be tween and guided by the upper parts of the said standards,and lockin -pins slidable in holes in the upper parts of t 1e saidstandards SAM WHEELHOUSE.
